http://yunkerlab.gatech.edu/uncategorized/new-paper-on-how-to-evolve-a-large-multicellular-body/#respondTue, 15 May 2018 17:11:26 +0000http://yunkerlab.gatech.edu/?p=278In our previous paper on the evolution of multicellularity, we showed that mechanical stresses develop during growth, eventually fracture clusters of cells into two pieces. Now we ask: when faced with this mechanical challenge, what is the best way to evolve large size? In our new paper, selected as a Rapid Communication in PRE, we show increasing bond strength does little, but modify how cells pack does a lot!

The fluctuation-dissipation theorem, derived by Harry Nyquist in the 1920’s, is essential to our understanding of equilibrium solids. The relationship between thermal fluctuations and mechanical responses provided a framework through which mechanical properties of solids were measurable and predictable. Our paper. The same may be possible for living films; we investigated it in collaboration with the Hammer lab, here at Georgia Tech’s School of Biological Sciences. Our work builds on a beautiful paper from Risler, Peilloux, and Proust, which investigated a model of apoptosis and reproduction in tissues.

These initial conditions have a large impact on the subsequent competition between strains, and can even switch which strain wins. Thus, the coffee-ring effect may ultimately impact evolutionary outcomes.
